X-Rated Greenawayesque Biscuit Tin

The X-rated additions to the lid, which was based on an illustration by Kate Greenaway, the early 20th-century children's illustrator, went unnoticed for years, until a vigilant shopworker spotted them. Production was halted immediately, but thousands of the tins had been sold.
One of the few remaining examples will be auctioned next week after being found in a collection built by a West Country aristocrat.
